The Fiber Optical Homogenizer (Laser Beam Stabilizers) is an all-fiber passive component which can efficiently homogenize speckle pattern and reduce unwanted modal noise (striations, hot spots, and beam non-uniformity) within a multimode optical fiber, producing a stable output beam that has fewer speckle hot spots and more uniform energy intensity profile. Lfiber’s Fiber Optical Homogenizer (Laser Beam Stabilizers) also mix light, which simplifies the combination of sources. They break up the input beam into smaller beamlets and reconfigure the modes of light.
